Weaker Polymer Bonds Produce Stronger Materials, Researchers Claim
We know that what doesn’t kill us makes us stronger — as Liam Neeson has taught us in almost every movie he’s ever made — but can weaker bonds in polymers actually make the material itself stronger? Yes, they can, claims a team of chemists from MIT and Duke University. They found that they could increase the tear resistance of a polyacrylate elastomer as much as 10-fold by using a weaker cross-linker to…
